Born in Brockville, Ontario Ladouceur played two years with the OHA's Brantford Alexanders. After signing as a free agent with the Detroit Red Wings, he spent a year each in the AHL and IHL working on his game. Ladouceur looked solid in 27 games as a rookie in 1982-83 before taking a regular turn on the blueline the next season. His solid play helped the club improve by 12 points and qualify for the post-season for the first time since 1978. Ladouceur played two and a half more years in Motown before he was traded to the Hartford Whalers for Dave Barr.

The steady rearguard played six and a half years with the Whalers and helped the team finish first in the Adams Division in 1986-87. Over the next five seasons, he was a reliable performer but the Whalers were caught in a rut, finishing fourth each year and losing in the first round of the playoffs. A respected presence on and off the ice, Ladouceur was the team's captain in 1991-92.

During the 1993 expansion draft, Ladouceur was claimed by the Mighty Ducks of Anaheim. He was a stabilizing influence on the young blueline and a role model off the ice. Ladouceur served as the team captain in 1994-85 then retired after playing 63 games in the 1995-96 season.
